Over time, what damages to the inside of my home can I anticipate
caused by exposure to Muriatic Acid fumes?  I am most curious about my
painted walls, carpet, fabrics and especially electronics such as TV's
and computers.

hmmm.I need a little more detail on the concentration.Is it still
there?Has it been neutralized?Is the smell there?Until I get more
detailed info, A short answer is the biggest problem will be stainless
steel corrosion.I'm assuming everything has been wiped down.Some quick
neutralizers would be banking soda of ammonia.For your peace of mind I
feel that most damage would be short term and very little long term
damage such as paint pealing.

I believe the most damage from Muriatic Acid is inflicted on living
things rather than non-living things. Fumes of muriatic acid tend to
evaporate as soon as they fly (at least, in a warm environment like my
location in Asia), so I doubt they cause any damage to house surfaces.
I haven't found any source though to substantiate this, so I give only
my personal experience with it.

Perhaps the following pages will be helpful to you.

Thanks for the response.  The problem I have is the acid was in my
house for 7-10 days.  It was used in a diluted form.   The contractor
worked 9.5 hours in my house trying to remove a seal from my brick
floors.  He applied the acid over the 9.5 hour period using an
industrial scrubber and did not attempt to neutralize the acid until
three days later.  By the way, I called the company that make the seal
to learn that is was acid resistant.  I don't know the concentration
but I know it was a large amount perhap 4-6 gallons of acid in total. 
Of course we ran the AC and Heater units during that 5-7 day period.

The house got quite a bit of exposure as I have light fixtures, door
knobs, and door hinges that are pitting and rusting in rooms that were
two rooms away from the work area.

I hope this gives you a better picture of my problem.  Frankly, I have
been unable to find anyone that has had a similar experience.

You can bet if you had pitting and rusting in rooms that were two
rooms away from the work area, that is not the only damage you have.
Any electronics could have similar damage and this could easily cause
early failure.
